Abstract

A display (100) comprising a plurality of LED chips (604), each LED chip (604) comprising a plurality of light emitting elements (606a-c). Each LED chip (604) is arranged such that a first light emitting element (606a) is configured to illuminate a sub-pixel, and a second light emitting element (606b) is configured to illuminate a sub-pixel using substantially the same wavelength of light as the first light emitting element. There is also described an LED chip, a display pixel, a controlling method, a computer device and a computer program for a display.

 a substrate; and 
 a plurality of discrete light emitting diode (LED) chips, each discrete LED chip of a triangular shape and including a plurality light emitting elements configured to emit light having the same color, the plurality of discrete LED chips arranged on the substrate to form display pixels of the display, each display pixel including:
 a first plurality of sub-pixels of a first color at corners of a first subset of the discrete LED chips, 
 a second plurality of sub-pixels of a second color at corners of a second subset of the discrete LED chips, and 
 a third plurality of sub-pixels of a third color at corners of a third subset of the discrete LED chips. 
 
 
     
     
       2. The display of  claim 1 , further comprising an optical film disposed on at least one of the discrete LED chips, the optical film configured to direct light from the at least one of the discrete LED chips. 
     
     
       3. The display of  claim 2 , wherein the optical film is configured to direct the light to a center of a display pixel. 
     
     
       4. The display of  claim 1 , further comprising a processor configured to provide power to one of the two light emitting elements of each sub-pixel. 
     
     
       5. The display of  claim 4 , wherein the processor is configured to provide power to a first light emitting element of the two light emitting elements responsive to a failure in a second light emitting element of the two light emitting elements. 
     
     
       6. The display of  claim 1 , wherein the plurality of discrete LED chips include the same type of semiconductor material. 
     
     
       7. The display of  claim 1 , wherein each of the plurality of discrete LED chips comprises Addressable Array Elements, each Addressable Array Element of a discrete LED chip providing a light emitting element. 
     
     
       8. The display of  claim 1 , wherein the substrate is configured to provide control and power to the plurality of discrete LED chips. 
     
     
       9. The display of  claim 1 , wherein the substrate includes an active matrix. 
     
     
       10. The display of  claim 1 , wherein the substrate includes a passive matrix. 
     
     
       11. The display of  claim 1 , wherein each discrete LED chip is located at an intersection of three adjacent display pixels. 
     
     
       12. The display of  claim 1 , wherein the plurality of light emitting elements of each discrete LED chip share a common cathode. 
     
     
       13. The display of  claim 1 , wherein a portion of the LED chips include quantum dot phosphors. 
     
     
       14. The display of  claim 1 , wherein a first portion of the plurality of discrete LED chips emit red light, a second portion of the plurality of discrete LED chips emit blue light, and a third portion of the plurality of discrete LED chips emit green light.
